Powder mixer sprayed with tungsten carbide is mainly used to improve the wear resistance, corrosion resistance and other properties of the powder mixer, to adapt to various harsh working environments, ensure stable and efficient operation of the mixer, and extend its service life. Its specific uses are as follows:
1. Enhance wear resistance
Dealing with particle wear: During operation, the internal components of the powder mixer frequently come into contact with a large amount of powder material, and the erosion of powder particles can cause surface wear of the components. After spraying tungsten carbide, its high hardness can significantly improve the wear resistance of the component surface. For example, in the process of mixing cement, ore and other powders, spraying tungsten carbide on the mixing blades, blades and other components can effectively resist the erosion and wear of powder particles, extend the service life of components, and reduce the frequency of equipment maintenance and replacement.
Reduce friction loss: The surface of tungsten carbide coating is relatively smooth, which can reduce the friction between powder materials and mixer components. This not only reduces wear caused by friction, but also reduces energy loss during the stirring process and improves stirring efficiency.
2. Improve corrosion resistance
Resistance to chemical erosion: In some chemical powder mixing scenarios, powder materials may be corrosive, such as powders containing acidic and alkaline components. Tungsten carbide has good chemical stability and can resist the erosion of various chemical substances. After spraying tungsten carbide on the mixer components, an effective protective barrier can be formed to prevent corrosion and ensure the normal operation of the equipment in harsh chemical environments.
Adapt to humid environments: For powder mixers working in humid environments, such as those in some food processing industries, tungsten carbide coating can prevent component rust, maintain equipment hygiene and safety, and avoid affecting powder quality due to rust.
3. Optimize surface performance
Improving powder flowability: The smooth surface of tungsten carbide coating helps to improve the flowability of powder in the mixer, making the powder material more evenly mixed. In the production of pigments, coatings, and other powders, this can ensure consistency in product quality and improve product quality.
Reduce material adhesion: After spraying tungsten carbide on the mixer components, it can reduce the adhesion of powder materials on the surface. In the powder mixing process of the pharmaceutical industry, avoiding material adhesion can reduce the risk of cross contamination, ensure drug quality and safety, and also facilitate equipment cleaning and maintenance.
4. Improve high temperature resistance performance
Adapt to high temperature conditions: In some high-temperature powder mixing processes, such as the mixing process before ceramic powder sintering, the mixer needs to withstand high temperatures. Tungsten carbide has a high melting point and good high temperature resistance. After spraying tungsten carbide, the agitator components can maintain stable physical and chemical properties in high temperature environments, preventing deformation and wear caused by high temperatures, and ensuring the normal operation of the agitator under high temperature conditions.
